method for screening of farbauszu00fcgen lentikularbildes and a method of producing a lentikularbildes on a printing substrate

摘要

it is a method for screening of a lentikularbildes farbauszu00fcgen with a lentikularfrequenz for the consideration of the lentikularbildes necessary lentikularlinsen (10) revealed.for each of the colour image by a rasterwinkel with a rasterfrequenz a amplitudenmoduliertes raster image are calculated, using the tangent of the rasterwinkels is a rational number.it is a in the vertical direction to the bildstreifen of lentikularbildes related rasterwinkel for a particular farbauszug established a few whole numbers (n, m)the ratio (m / n) is equal to the tangent of the rasterwinkels isand the rasterfrequenz of farbauszugs as the product of the lentikularfrequenz and the square root of the sum of the squares of two integers is calculated.in order to manufacture of lentikularbildern on a printing substrate, the calculated colour image by this method each for a printing form and printing in the exposed exposeda printing machine in zusammendruck on a printing substrate printed, so that a multicoloured lentikularbild on the printing substrate is formed.
